Hello, i have 17+ years experience in 3d modeling, texturing, rendering, with focus on photorealistic renderings, i use 3dmax, blender, inventor, zbrush, vray and cycles.
As you can see in my portfolio, i use 3d to show my clients products, and i am a product designer myself, so i understand the issues and needs of my clients when it comes to product showcase.
I have a deep understanding of materials, being cardboard, metal, glass, plastic or wood, i can represent prototypes with a high level of realism. In the case of your project, i think is convenient even to 3d print a small scale model. I have my own 3d printer and work with shapeways so you can have a real 3d printed version of your lab!
I hope to hear from you and wish you good luck with the project!
Ivan
